The study aims to assess whether mortality and VT/VF events decreased in patients who received ICDs during different time periods (2007–2010, 2011–2014, and 2015–2018). Time periods were chosen based on the establishment of the Arrhythmia Service in 2011. 001) and the combined outcome ( p  = .009).

With 2nd- or 3rd-degree AV block — the atrial rate should be regular ( or at least almost regular — if there is an underlying sinus arrhythmia ) — but it should be clear from the timing of the RED arrows in Figure-2 — that no on-time P wave occurs between beats #1-2; #3-4; #5-6; #7-8; #9-10; #11-12.

KEY Point: When most beats in an arrhythmia are regular, but some are not — the best CLUE to interpretation often resides in looking for a “ break ” in the rhythm ( such as is seen between beats #13 and 14 in Figure-2 ). The simple step of labeling all of the obvious P waves — is surprisingly helpful in evaluating the rhythm.

Realizing that slight variation in the P-P interval is common ( known as sinus arrhythmia ) — the PINK arrows in Figure-3 suggest the probable location of underlying sinus P waves. Certain complex arrhythmias may have more than a single plausible rhythm interpretation. This is precisely what we see in Figure-4.

Note also that the P-P interval between successive P waves ( vertical RED lines ) is similar, albeit not quite equal ( ie, There is slight sinus arrhythmia ).

I find it helpful in sorting out complex arrhythmias to search out P waves at an early point in the process. Is There a Regular P Wave Rhythm?

Prior to Mizusawa's study, it was thought that the incidence of syncope, arrhythmia, or SCD in this cohort was low [7]. In light of the risk of arrhythmia events observed in the Mizusawa trial, a formal EP study might be reasonable to obtain in those with fever induced asymptomatic Brugada ECG changes to help risk stratify these patients.
